A woman at a brokerage’s terminal in the ’70s, using one of the last ever ticker machines. It was considered “high speed” at 900 characters per minute.

Here’s the description from EliteTrader: “Here is a girl working on a teletype one of the KSR series, notice the two Ultronic’s and the high speed 900 series ticker. (900 characters per minute) Those were the last ever ticker machines built. Oh and back in the days you had different tapes then in the mid 1970s and up you had the consolidated tape but you still had the last sale tape and the bid and ask tape.”

By the ’80s, the big-time tech player was Quotron. Here’s what one of their terminals looked like on Black Monday, October 19, 1987.

Quotron was a household name back in the day. They were eventually sold to Reuters.
